Yes, but the expired patent mentioned is still expired: April 1977 J. Flanagan (of BTL) applied for a patent on Packet Transmission of Speech. July 1978 US patent 4,100,377 granted to J. Flanagan. And this classic patent is still unexpired: May 1988 US patent 4,748,620, Time stamp and packet virtual sequence numbering for reconstructing information signals from packets granted to Harry W. Adelmann and James D. Tomcik I haven't read either of these, but I'd guess these are the baseline intellectual property for packetizing audio, and newer patents build on them -- if you're worried about IP on this issue, start worrying with these, not Gibson or Digigram ... ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------
